Hi, the problem is not that the target CPU is old, but rather that according to the (former?) maintainer, there are no users left: https://www.mail-archive.com/qemu-devel@nongnu.org/msg605024.html So it got marked as deprecated in this commit here: https://git.qemu.org/?p=qemu.git;a=commitdiff;h=d84980051229fa43c96b3 Without maintainer and without users, there is no point in keeping this target, is there?
